There is still a problem with Google Chrome and Chromium, I have found the root cause but I need your help to reproduce this bug under Microsoft Windows and Mac OS X. You have to click "Open" or "Always open this kind of file" to run a Java application using Java Web Start but it works fine only the very first time:https://code.google.com/p/chromium/issues/detail?id=135363

Thank you ra4king. I will try with Oracle JVM tomorrow. If it comes from NetX, I will have to fix this bug by myself. Otherwise, I will suggest Google to use - or _ instead of " " in the filename and Java Web Start will be happy.
